Here is a build I did a while ago. The tractor unit was heavily modified with the chassi from two kits and some scratchbuilding. I also added a scratch built trailer to give the overall look a some-what outrageous look. At least I think so. The trailer inspiration was taken from two trailers, one from the net and the other from a trailer around my area. Added a couple more details after these pics were taken but will upload them later. Here are the photos.
Oh, and BTW, this took first prize and Gold at the 08 Stockholm IPMS Openin March:
